I've been sampling a fairly wide variety of sources in various parts of the global supply chain, and my synthesis of what they're saying is that we probably won't *consistently* have the ready availability of "stuff" (both electronic and not) we had pre-pandemic, for the rest of my career (10-15yrs), and maybe not in the lifetimes of anyone reading this today, either.
For those who may have forgotten:
That was the *sole* supplier of extreme ultraviolet lithography machines for every major chip manufacturer on the planet.
Chip shortages will only get worse for the next several years. The light at the end of the tunnel is unfortunately *not* coming from an ultraviolet lithography machine. :(
